[PATCH v1 07/10] OMAP3: hwmod: add dev_attr for McBSP sidetone

[Kishon Vijay Abraham I <kishon@ti.com>]

Add device attribute for OMAP3 McBSP sidetone hwmod data

Discussions related to this change can be found in the following url:
https://patchwork.kernel.org/patch/233221/

Also add a revision member inorder to facilitate the driver to
differentiate between different cpu's.
